As-Salaam alaykum,
Brother, in the first instance you have no reason to be mad. The Noble Prophet Muhammad, Sallallahu alaihi Wasllam, the Leader of Mankind and Jinn, told us NOT to be angry. And anger is the prime mover to being mad... so, when you do not become angry, you will hardly be mad, as it were. But where you/we become angry, we should immediately be patient, that is:--

(a) Not to complain about whatever happens to us, even if supposedly 'painful' to us

(b) Be satisfied with what is Decreedby Allah, Azzah Wa Jallah, to happen to us.

Aggression or aggressiveness is not allowed in Islam. We must control our anger and Allah will give the reward in eternal life. Sometimes, I heard anger is allowed, can you please share these points here.
